Sheet pile combi wall, or in other words, it is called as combined wall. Normally the combi wall is a combination of steel sheet piles and H piles or tubular pipe piles.

Sheet pile combi wall is providing a very high section performance which has been widely used in harbor / port constructions and shipyard constructions where there is a requirement of long piles and high section modulus sheet pile retaining walls.

The steel sheet piles in combi walls could be Z sheet piles, U sheet piles and even Omega sheet piles, but Z sheet pile is the most traditional section that has been used in combi wall systems.

An HZ combi wall system consists of steel H piles that withstand most of the loading and a pair of intermediary Z sheet piles in between, which transmit pressure loads to the H piles. The H Pile is fabricated or assembled H pile of which the dimensions could be customized by the client. The key accessory for the steel H pile is the flat pile, which would be welded to the H piles like a “hat”, with interlocks at both side, acting as the interlocking system for the H pile.An OZ combi wall system consists of steel tubular pipe pile and Z sheet pile. Interlocks would be welded to both side of the steel piles, forming the interlocking system to connect the pipe piles with the Z sheet piles.Shunli Steel Group is offering various combinations of sheet piles to fulfill the requirements of worldwide projects.
